Buy Oxycontin OP 20mg in UK Online
Oxycontin OP 20mg is a modified-release (prolonged-release) tablet containing 20 mg of oxycodone hydrochloride, a strong opioid analgesic used to treat moderate to severe cancer pain and other severe pain requiring continuous treatment with a strong opioid. The tablet is designed to release oxycodone gradually over approximately 12 hours, providing sustained pain relief.
In the United Kingdom, OxyContin is a Prescription Only Medicine (POM) and a Schedule 2 Controlled Drug. Because of its potential for misuse, dependence, addiction, respiratory depression, and overdose, it should only be used under the supervision of a qualified healthcare professional.
What Is OxyContin OC 20mg?
Each modified-release tablet contains:
- Active ingredient: Oxycodone hydrochloride 20 mg
- Medicine class: Strong opioid analgesic
- Dosage form: Modified-release (extended-release) tablet
According to the UK Summary of Product Characteristics, the 20 mg tablet is pink, round, convex, and marked “OC” on one side and “20” on the other.
How Does Oxycodone Work?
Oxycodone works by attaching to mu-opioid receptors in the brain and spinal cord. This action:
- Reduces the perception of pain
- Changes the emotional response to pain
- Provides continuous pain relief for approximately 12 hours
Like other opioid medicines, oxycodone can also slow breathing, especially when taken in excessive doses or together with alcohol or other sedative medicines.
Medical Uses
Healthcare professionals may prescribe OxyContin OC 20 mg for:
- Severe chronic pain
- Moderate to severe cancer pain
- Pain associated with advanced illnesses
- Severe pain requiring continuous opioid therapy
OxyContin modified-release tablets are not intended for breakthrough pain or occasional (“as needed”) pain relief. They are usually taken every 12 hours.
Availability in the UK
Oxycontin OP 20mg is available only with a valid prescription.
As a Schedule 2 Controlled Drug:
- Prescriptions are subject to strict legal requirements.
- Treatment should be reviewed regularly.
- The medicine should never be shared with another person.
Dosage
The correct dose depends on:
- Severity of pain
- Previous opioid treatment
- Age
- Liver and kidney function
- Other medical conditions
- Other medicines being taken
For adults who have not previously taken strong opioids, the usual starting dose is 10 mg every 12 hours, although 5 mg every 12 hours may be appropriate for some patients to reduce side effects. The 20 mg strength is generally prescribed after careful dose adjustment when clinically appropriate rather than as an initial dose.
Important instructions:
- Take the medicine exactly as prescribed.
- Swallow the tablets whole with water.
- Do not crush, chew, split, or dissolve the tablets. This can rapidly release the entire dose, greatly increasing the risk of a potentially fatal overdose.
Benefits of Oxycontin OP 20mg
When prescribed appropriately, Oxycontin OP 20mg may help:
- Provide continuous pain relief for around 12 hours
- Improve comfort and mobility

These symptoms may indicate an opioid overdose or another serious medical emergency.
Dependence, Tolerance, and Addiction
Long-term oxycodone treatment may lead to:

If treatment needs to be stopped, the dose should usually be reduced gradually under medical supervision to minimise withdrawal symptoms.
Drug Interactions
Tell your healthcare professional about all medicines and supplements you take.
Important interactions include:
- Other opioid medicines
- Benzodiazepines
- Sleeping tablets

These combinations can significantly increase the risk of excessive sedation, respiratory depression, coma, and overdose.

Alcohol increases the risk of:
- Excessive drowsiness
- Dangerous respiratory depression
- Overdose
- Potentially fatal complications
Driving and Operating Machinery
Oxycodone may impair your ability to:

Do not drive or use machinery if you feel sleepy, dizzy, or unable to concentrate safely. Follow UK legal guidance regarding driving while taking opioid medicines.
Pregnancy and Breastfeeding
If you are pregnant, planning a pregnancy, or breastfeeding, speak with your healthcare professional before taking oxycodone.
Long-term opioid use during pregnancy may cause neonatal opioid withdrawal syndrome, requiring specialist care after birth.
